GAZA, March 10--U.N. troops used tear gas and fired in the air today to break up a demonstration by thousands of Arabs demanding return of Egyptian administration to the Gaza Strip. U.N. headquarters announced several demonstration leaders were arrested after the U.N. soldiers were stoned as they drove the crowd down Gaza's main street.

Yugoslav U.N. troops, who had been withdrawn from the Gaza Strip earlier, were called back to help deal with the demonstration, said Maj. Gen. E. L. M. Burns, U.N. force commander. Belgrade radio announced earlier that Yugoslav units had left the strip. It gave no reason, but the Yugoslav government had hinted its troops would be pulled out of the strip if Egypt objected to U.N. control of the territory.

Twenty-six beach homes were destroyed on Kauai Island by the waves, caused by two massive under the-ocean earthquakes near the Aleutians.
